Zend\Navigation

Zend\Navigation is a component for managing trees of pointers to web pages. Simply put: It can be used for
creating menus, breadcrumbs, links, and sitemaps, or serve as a model for other navigation related purposes.

A page (Zend\Navigation\AbstractPage) in Zend\Navigation – in its most basic form – is an object that
holds a pointer to a web page. In addition to the pointer itself, the page object contains a number of other
properties that are typically relevant for navigation, such as label, title, etc.

A navigation container (Zend\Navigation\AbstractContainer) is a container class for pages. It has methods
for adding, retrieving, deleting and iterating pages. It implements the SPL interfaces RecursiveIterator
and Countable, and can thus be iterated with SPL iterators such as RecursiveIteratorIterator.

Classes in the Zend\Navigation namespace do not deal with rendering of navigational elements. Rendering is done
with navigational view helpers. However, pages contain information that is used by view helpers when rendering,
such as; label, class (CSS), title, lastmod and priority properties for sitemaps, etc.

Read more about rendering navigational elements in the manual section on navigation helpers.
